Project Cornerstone's mission is to educate the public about the importance of local construction aggregates (i.e., sand, gravel and crushed stone) through hands-on learning in Science, Technology, Engineering and Mathematics (STEM). Construction aggregates are used to build roads, houses, schools and all other infrastructure; they are the cornerstone of our communities.

Robertson's, a San Diego construction aggregate producer, was seen pouring concrete for the new Copley-Price Family YMCA in the Mid City community of San Diego. The facility is scheduled to open in January 2015.
